Current scientific literature refutes the claim that LSD and tryptamines are neurotoxic, instead highlighting their low physiological toxicity and promising therapeutic applications.
The claim asserts that LSD and tryptamines are neurotoxic rather than harmless. The retrieved papers consistently characterize classic psychedelics and tryptamines (such as LSD, DMT, and psilocin/psilocybin) as compounds with low physiological toxicity, good safety profiles, and promising neuroplastic and therapeutic properties for psychiatric conditions, rather than neurotoxic agents. Therefore, the evidence firmly refutes the claim.
